Hi.

I am puzzled but I am sure it will be obvious to you.

I have
  • drawn 2 circles, touching at the circumference.
    selected them both
    drawn a small box around the rotation centre (just so that I can see what is happening)
    ctrl-K
    rotated the 2 new circles by 10 degrees

and the rotation centre has moved. I do not undertand why.Click image for larger version.  Name: Screenshot (57).jpg  Views: 114  Size: 53.2 KB  ID: 123874Click image for larger version.  Name: Screenshot (58).jpg  Views: 121  Size: 50.5 KB  ID: 123875
